Frequently Asked Questions
What is a 40GBase-LR4 QSFP+ transceiver used for?
A 40GBase-LR4 QSFP+ transceiver is used for high-speed, long-distance fiber optic connectivity in data centers, enterprise networks, and carrier environments. It supports 40 Gbps transmission over single-mode fiber up to 20 km, making it ideal for campus interconnects and data center-to-data center links.
Is this QSFP+ module compatible with HP network equipment?
Yes, this transceiver is HP® certified compatible and designed to work seamlessly with HP network switches and infrastructure. It meets TAA compliance requirements for government and enterprise procurement.
What does DOM mean on a fiber optic transceiver?
DOM (Digital Optical Monitoring) allows real-time monitoring of transceiver performance metrics including optical power levels, temperature, and voltage. This enables proactive network management and faster troubleshooting of connectivity issues.
Can this 40GBase-LR4 transceiver work with multimode fiber?
No, this module is specifically designed for single-mode fiber (SMF). Using it with multimode fiber will result in signal degradation and connection failures. Always verify your fiber type before installation.
